ICE-CUTTING MACHINE.

Speccation of Letters Patent.

Patented March 5, 1907.

Application filed Januar) 1.8, 1906. Serial N o. 296.699. l

To all whom it may concern,.-

Be it known that I, EVAN F. EVANS, a citizen of the United States, residing at Burlington, in the county of Des Moines and State of Iowa, have invented certain new and useful Improvements in Ice-Cutting Machines; and I do declare the following to be. a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in machines for cutting ice upon a river, pond, or other bod of water by horse-power or any other suitab e power.

The object of the invention is to provide a machine of this character which will be simple in construction, durable in use, efficient in operation, and comparatively inexpensive to manufacture. y

With the above and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure l is a side elevation of an ice-cutting machine constructed in accordance with my invention, and Fig. 2 is a top plan view of the same.

Referring to the drawings by numeral, l denotes my improved ice-cutting machine, which is here shown as adapted for being moved over ice upon the surface of a river, pond, or the like by means of one or more horses or draft-animals. The machine comprises a main shaft or axle 2, which is journaled in a suitable frame 3, and has secured upon its end supporting and drive wheels 4. The latter have upon their peripheries spurs 5 to prevent them from slipping upon the ice when the machine is drawn forwardly by horses or by any suitable power-operated propelling mechanism.

The frame 3, as shown, consists of two substantially right-angular side sections 6, which are suitably connected and have at their lower ends rearwardly-extending runners or drags 7. The latter are connected by a transversely-extending platform 8, upon which the operator may stand. Mounted to swing from the shaft 2 are two arms or hangers 9, which have journaled in their outer ends a transverse shaft 10. Upon the latter, adjacent to its ends, are secured rotary or circular saws 1l, which are adapted to cut the ice over which the machine is drawn.

These saws may be rotated by any suitable gearing arranged between the shafts l() and 2 but I preferably secure upon the wheels 4 gear-wheels l2, which mesh with pinions 13, loosely mounted upon the shaft 1U.

Formed upon or screwed to the pinions I3 are small sprocket-wheels 13a, which are connected by sprocket-chains 13b to sprocketwheels 13C, secured to sleeves 13d, which are loosely mounted upon the shaft or axle 2 and from which extend the hangers or arms 9. Also secured to the sleeves I3d are large sprocket-wheels 13e, which are connected by sprocket-chains 13I to small sprocket-wheels 13g, secured upon the shaft l0. It will be seen that by means of this gearing the shaft 1t), which carries the saws, will be rapidly rotated as the machine is drawn forwardly by one or more draft-animals. 'I'he depth of the cuts made by the saws 1 1. may be regulated by raisine and lowering the shaft IO and its supporting-arms 9, and I preferably accomplish this by pivotally connecting to the shaft It), adjacent to its ends, rack-bars 14, which have their upper rear ends slidably mounted in suitable guides 15. The teeth ofthe rack-bars 14 mesh with pinions 16, secured upon a shaft 17, which extends transversely and is mounted in bearings in the angles of the right-angular sides 6 of the frame. A suitable hand-wheel 1S is provided upon the shaft 17 to permit it to be rotated for the purpose of adjusting the saws 1l. It will be seen that when the machine is drawn forwardly by one or more draftanimals, which may be connected in any suitable manner to the shaft 2 or the frame 3, the saws] l will be rotated to cut the ice over which the machine travels.

From the foregoing description, taken in connection with the accompanying drawings, the cor struction and operation of the invention will be readily understood without requirino1 a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Iletters Patent, is

An ice-cutting machine comprising a frame, consisting of two substantially rightangular connecte d side` portions, a main shaft journaled in the forward ends of said ICO side portions, supporting and drive Wheels upon said shaft, runners upon the lower rear ends of said side portions of the frame, a

naled in said arms, a circular saw upon said saw-shaft, a sprocket-Wheel lixed to said saw-shaft, a sleeve upon said main shaft, a sprocket-Wheel fixed to said sleeve, a sprocket-chain connecting said sprocketwheels, a second sprocket-Wheel fixed to said sleeve, a sprocket-Wheel loose upon said sawshaft, a sprocket-chain connecting the latter and said second sprocket-Wheel upon said sleeve, a pinion lixed to said loose sprocket- Wheel and loose upon said saw-shaft, a gear fixed to one of said driving-Wheels and in mesh with said pinion, an operating-shaft journaled in the angles of the side portions platform connecting said runners, swinging arms upon said niain shaft, a saw-shaft ]ourof said frame, a pinion upon the last-nientioned shaft, a guide, rack-bars pivotally connected to said saw-carrying shaft, slidably mounted in said guide and engaged in said pinion, and a hand-Wheel upon said op- @rating-shaft, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
